Easy Come, Easy Go

I'm on vacation this week. I've got the in-laws from out of state visiting. Monday we went to the casino. My wife and her sister and mother played the slots, I headed straight for blackjack. $5 minimum, so I started out with $20 in chips. Within just a few hands, I had doubled my money. I then got up and went to the slots, where I piddled around for a little while. I kept coming back to blackjack, playing a couple of hands, moving up and down, leaving when I lost too many hands in a row. I hit a decent payout on a slot machine, and I was having a good time. At some point I went back to blackjack, and got on a losing streak. Eventually I was down to nothing. I had run out of slot money, as well. I took a couple of tokens from my wife, parlayed those into enough for another blackjack hand, and won! I was excited. I put $5 down, drew a 20 with the dealer showing 3. Naturally, I stood. She turns over an 8, for a total of 11. You can imagine what happened next. She draws a 10 for 21. I was so flabbergasted, I actually blurted out, "you've got to be kidding me!" I played my last $5 and lost. I went to the casino with $50, had probably doubled my money at one point, and came home empty handed (and headed). I should have quit while I was ahead.
